To apply or not to apply: That is the intern applicant's first question.

What are the variables influencing intern applicants' decisions to apply to particular internship training programs? This single-site study investigated the decision-making process of 106 potential intern applicants who decided not to apply to an internship program. Results indicate that a variety of factors (e.g., postponing internship training, sense of limited fit with the program or location, financial or partner concerns) influenced the potential applicants' decisions.

"Are clinical psychologists prepared for service and research with ethnic minorities?: Report of a decade of progress": Comment.

Comments on M. E. Bernal and F. G. Castro's (see record 1995-03295-001) longitudinal study of the status of training of clinical psychologists for service and research with ethnic minority populations. Cancio et al contend that Bernal and Castro did not answer the question the study originally proposed. Also, the study was not a true longitudinal study because the sample had changed. Questions are raised regarding the authors' decision to present the definition and clarification of cultural proficiency. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A response to Clark and Elliott.

Comments that problems with the experimental design and procedures may threaten the internal and external validity of the study by L. Clark and S. N. Elliott (see record 1989-24134-001) examining knowledgeable teachers' evaluations of pretreatment acceptability and perceived effectiveness of 2 social skills treatment procedures. Suggestions are given for increasing the study's validity. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Nonlinear surface impedance of YBCO thin films: Measurements, modeling, and effects in devices

High-T _c thin films continue to be of interest for passive device applications at microwave frequencies, but nonlinear effects may limit the performance. To understand these effects we have measured the nonlinear surface impedanceZ _s in a number of YBa₂Cu₃O_7–x thin films as a function of frequency from 1 to 18 GHz, rf surface magnetic fieldH _rf to 1500 Oe, and temperature from 4 K toT _c . The results at lowH _rf are shown to agree quantitatively with a modified coupled-grain model and at highH _rf with hysteresis-loss calculations using the Bean critical-state model applied to a thin strip. The loss mechanisms are extrinsic properties resulting from defects in the films. We also report preliminary measurements of the nonlinear impedance of Josephson junctions, and the results are related to the models of nonlinearZ _S . The implications of nonlinearZ _S for devices are discussed using the example of a five-pole bandpass filter.The authors thank Dr. Alfredo Anderson of Lincoln Laboratory for many YBCO films and technical discussions concerning film properties. We thank Dr. J. Halbritter for numerous discussions and ideas. We thank also Prof. S. Sridhar, B. Willemsen, N. Belk, and Dr. J. Herd for technical discussions. We are deeply indebted to R. P. Konieczka and D. J. Baker for resonator assembly and technical support. Drs. R. W. Ralston, T. C. L. G. Sollner, and P. Carr are thanked for technical guidance and support.     

Analyse der bei den chemischen reaktionen von vernetzten makromolekularen stoffen gewonnenen zeit-umsatz-kurven

A proposal of approximating conversion curves is given using the relation α = 1 ? exp (a₁τ^a2). The calculation of the reaction rate constant and the diffusion coefficient is proposed by means of that relation. This diffusion coefficient refers to the diffusion of the reacting liquid components into the hydrophobic skeleton of the crosslinked macromolecular substance. The proposal is carried out for reacting crosslinked macromolecular substances in form of spheres, plates and cylinders.     

Textile flammability testing: Appropriate levels for moisture content of specimens

This study was performed to establish the appropriate moisture level for textile flammability test specimens. Three investigations were carried out: into the effect of the level of humidity in dwellings; into the moisture content of garments worn at various distances from the body; and into the effect of relatively short exposures to heat on the moisture content of fabrics (simulating the case of a person standing in front of an open fire or space heater). The moisture content of ambient air in dwellings was found to be primarily governed by the moisture content of the air outside and can be quite low, ten to twenty percent, especially in winter (unless, of course, humidifying equipment is used). The moisture content of garment parts which are at some distance from the body (e.g., the loosely fitting parts of skirts) is governed by the relative humidity of the room. Closely fitting parts are more likely to be exposed to ignition sources than closely fitting parts. Fabric specimens exposed at a short distance from an electric space heater had moisture contents similar to specimens which has been oven-dried and cooled in a desiccator. The results of these studies indicate that oven-drying is a reasonable conditioning requirement for testing the flammability of apparel and home furnishing fabrics.     

Stressors of professionals and trainees at APA-approved counseling and VA medical center internship sites.

The purpose of this study was to assess the perceived stress experienced by professionals and trainees during psychotherapy and supervisory activities at American Psychological Association-approved university counseling center and Veterans Administration (VA) medical center internship sites. One hundred thirty-five staff members (90 professionals, 43 interns, 2 practicum students) from fourteen VA centers and 144 staff members (79 professionals, 37 interns, 28 practicum students) from twelve university counseling centers responded to a questionnaire used to assess perceived stress. In data analysis, we compared the stress of professionals and trainees. In secondary analysis, we compared stressors of staffs at VA and counseling centers. We also investigated beliefs that contributed to the stress experienced. Results indicate that professional staff find their experiences less stressful than do interns, who find their experiences less stressful than do practicum students. Also, VA staff members reported less stress than did counseling staff. Results are compared with previous research in this area, and previous conclusions regarding the universality of stressors are addressed.

Anwendung einer Näherungsmethode zur Verarbeitung der Zeit-Umsatz-Kurven

The procedure that makes possible to evaluate the time conversion curves of the chemical reaction between the liquid reactant and the crosslinked macromolecular substance was proposed in a previous work. In the present work the given procedure is described, further developed, and mutually compared at the example of the alkaline hydrolysis of the copolymer beads from ethyl acrylate, acrylonitrile, and divinylbenzene.     

Building Orientation and Wind Effects Estimation

The methodology for estimating wind effects presented in this paper is based on the database-assisted design approach. It accounts for the effects of wind directionality, for the effects of the uncertainties in the parameters that determine wind effects, and for the effects of building orientation. The methodology yields estimates of wind effects that are far more realistic than those based on the conventional building code approach, which disregards uncertainties in those parameters, as well as the effects of wind directionality and building orientation, or accounts for these effects through the use of a blanket reduction factor. The pilot software on which the calculations presented in this paper are based is a first step toward modern computer-intensive electronic standards wherein wind loads can be calculated by using database-assisted reliability-based calculations of wind effects. We believe such standards will go a long way toward achieving significantly safer and more economical buildings in regions affected by strong winds.
